Munin client node error:

Can someone help me here..

Answer 1

My regex on client (munin-node.conf) messed up.

Add munin server IP to client munin-node.conf

allow 10.202.30.210

restart munin-node service.

It worked this time

[root@nagios ec2-user]# telnet ec2-184-73-97-201.compute-1.amazonaws.com 4949
